3.0 Applicable standards and reference documentation

The drives documented in this manual have been developed as system peripherals to the highest standards of design and construction. The drives depend on host equipment to provide adequate power and environment for optimum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas o f safety, power distribution, shielding, audible noise control, and temper­ature regulation. In particular, the drives must be securely mounted to guarantee the specified performance characteristics. Mounting by bottom holes must meet the requirements of Section 9.4.

3.1 Standards

The Savvio family complies with Seagate standards as noted in the a ppropriate sectio ns of this manual and the Seagate FC Interface Manual, part number 100293070.
The drives are recognized in accordance with UL 60950 and CSA 60950 as tested by UL(CSA) and EN60950 as tested by TUV.

3.1.1 Electromagnetic compatibility

The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to use. As such the drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC Rules and Regulations nor the Radio Interference Regulations of the Canadian Department of Communica­tions.
The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides reasonable shielding. The drive is capable of meeting the Class B limits of the FCC Rules and Regulations of the Canadian Department of Communications when properly packaged; however, it is the user’s responsibility to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be required if the enclosure does not provide adequate shielding. If the I/O cables ar e external to the enclosure, shielded cables should be used, with the shields grounded to the enclosure and to the host controller.

As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of those integrating the drive within their systems to perform those tests required and design their system to ensure that equipment operating in the same system as the drive or external to the system does not adversely affect the performance of the drive. See Tables 2 through 5, DC power requirements.

3.2 European Union Restriction of Hazardous Substances (RoHS)

The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical substances, including Lead (Pb), in electronic products effective July 2006.
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the rep­resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier contracts require compliance with our ch emical substance restrictions, and our suppliers document their compliance with our requirements by providing material conten t declarations for all p arts and materials for the disk drives documented in this publication. Current supplier declarations include disclosure of the inclusion of any RoHS-regulated substance in such parts or materials.
Seagate also has internal systems in place to ensure on going compliance with the RoHS Directive and all laws and regulations which restrict chemical content in electronic products. These systems include st andard ope rat­ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora­tory analytical validation testing, and an internal auditing process to ensure that all standard operating procedures are complied with.

4.0 General description

Savvio 10K.5 FC drives provide high performance, high capacity dat a storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputer s. Savvio 10K.5 F C drive s suppo rt 4-Gb Fibre Channel which can transfer data at up to 800MBs per second and 1600MBs per second in dual­loop configurations.
Savvio 10K.5 FC drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual which describes the general interface characteristics of this drive. Savvio 10K.5 FC drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.
Note. Never disassemble the HDA and do not attempt to service items in the sealed enclosure (h eads, media, actuator,
etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for any reason voids your warranty.
Savvio drives use a dedicated load/u nload zo ne at the o utermost radius of the media to eliminate the possibil­ity of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp load/ unload when power is removed from the drive.
An automatic shipping lock prevents potential damage to the heads and disks that results from movement dur­ing shipping and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.
The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides excellent performance with minimal power dissipation.

4.5 Formatted capacities

Sta ndard OEM mode ls are for matted to 512 bytes pe r block. The sector size is select able at format time. Use rs having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed.
To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two modes:
1. Seagate designs specify capacity points at certain sector sizes that Seagate guarantees current and future roducts will meet. We recommend customers use this capacity in their project planning, as it ensures a
p stable operating point with backward and forward compatibility from generation to generation. The current guaranteed operating points for this product are:

2. Seagate drives also ma y be used at the m aximum availa ble cap acity at a given sector size, but the excess
capacity above the guaranteed level will vary between 10K and 15K families and from generation to gener­ation, depending on how each sector size actually formats out for zone frequencies and splits over servo
ursts. This added capacity potential may range from 0.1 to 1.3 percent above the guaranteed capacities
b listed above. Using the drives in this manner gives the absolute maximum capacity potential, but the user must determine if the extra capacity potential is useful, or whether their assurance of backward and for­ward compatibility t
akes precedence.
8 Savvio 10K.5 FC Product Manual, Rev. D

4.6 Programmable drive capacity

Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select Parameter List table in the SCSI Co mmands Refe ren c e Manu al . Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall not change the capacity it is currently formatted to have. A number in the number of blocks field that is less than the maximum number of LBAs changes the total drive capacity to the value in the block descriptor number of blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity.

4.7 Factory-installed options

You may order the following items which are incorporated at the manufacturing facility during production or packaged before shipping. Some of the options available are (not an exhaustive list of possible options):
• Other capacities can be ordered depending on sparing scheme and sector size requested.
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit damage. Units shipped individually require additional protection as p rovided by the sin gle unit shipping pack. Users planning single unit distribution should specify this option.
•The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM drive shipped, but extra copies may be ordered.

5.3 Start/stop time

If the Motor Start option is disabled, the drive becomes ready within 20 seconds after DC power is applied. If a recoverable error condition is detected during the st art sequence, the drive executes a recovery proced ure and the time to become ready may exceed 20 seconds. During spin up to ready time, the drive responds to some commands over the FC interface in less than 3 seconds after application of power. Stop time is 30 seconds (maximum) from removal of DC power.
If the Motor Start option is enabled, the internal controller accepts the commands listed in the Fibre Channel Interface Manual less than 3 seconds after DC power has been applied. After the Motor Start command has been received, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure). The Motor Start command can also be used to command the drive to stop the spindle.
There is no power control switch on the drive.

5.4 Prefetch/multi-segmented cache control

The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch and cache operations ar e independent features from the standpoint that each is enabled and disabled independently using the Mode Select command; however, in actual opera­tion, the prefetch feature overlaps cache operation somewhat as described in sections 5.5.1 and 5.5.2.
All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Section 10.3.2
Savvio 10K.5 FC Product Manual, Rev. D 11

5.5 Cache operation

Note. Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits.
Of the 64 Mbytes physical buffer space in the drive, approximately 30,000 kbytes are available as a data cache. The remaining buffer space is reserved for internal drive use.
The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit in the FC Interface Manual ), data requested by the host with a read command is retrieved from the buffer , if po ssible, before any disk acce ss is initiated. If cache operation is not enabled, the buffer is still used, but only as circular buffer segments during disk medium read operations (disregarding Prefetch operation for the moment). That is, the drive does not check in the buffer segments for the requested read data, but goes directly to the medium to retrieve it. The retrieved data merely passes through some buffer segment on the way to the host. All data transfers to the host are in accordance with buffer-full ratio rules. See the explanation provided with the information about Mode Page 02h ( disconnect/reconn ect control) in the Fibre Channel Interface Manual.
The following is a simplified description of the prefetch/cache operation: Case A—read command is received and all of the requested logical blocks are already in the cache:
1. Drive transfers the requested logical blocks to the initiator.
Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache:
1. The drive fetches the requested logical blocks from the disk and transfers them into a segm ent, and then
from there to the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.
2. If the prefetch feature is enabled, refer to section 5.5.2 for operation from this point.
Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical blocks. The drive dynamically creates and removes segments based on the workload. The wrap-around capa­bility of the individual segments greatly enhances the cache’s overall performance.
Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value 0XFFFF
is always reported regardless of the actual size of the segment. Sending a size specifi cation using the Mode Select command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte 2, bit 1) is set to one, the drive responds as it does for any attempt to change an unchangeable parameter.
12 Savvio 10K.5 FC Product Manual, Rev. D

5.5.1 Caching write data

Write caching is a write operation by the drive that make s use of a drive b uffer storage area wher e the da ta to be written to the medium is stored while the drive performs the Write command.
If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made avail­able for future read cache hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or changed independently, having nothing to do with the state of RCD. When a write command is issued, if RCD=0, the cache is first checked to see if any logical blocks that are to be written are already stored in th e cache from a previous read or write command. If there are, the respective cache segments are cleared. The new data is cached for subsequent Read commands.
If the number of write data logical blocks exceed the size of the segme nt being written into, when the end of the segment is reached, the data is written into the beginning of the same cache segment, overwriting the da ta that was written there at the beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium.
If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been transferred into the cache, but before the data has been written to the medium. If an error occurs while writing the data to the medium, and Good status has already been returned, a deferred error will be gen­erated.
The Synchronize Cache command may be used to force the drive to write all cached write dat a to the med ium. Upon completion of a Synchronize Cache command, all data received from previous write commands will have been written to the medium.
Tables 19 through 22 show the mode default settings for these drives.

5.5.2 Prefetch op e r at io n

If the Prefetch feature is enabled, data in contiguous logical blocks on the disk immediately beyond that which was requested by a Read command are retrieved and stored in the buffer for immediate transfer from the buf­fer to the host on subsequent Read commands that request those logical blocks (this is true even if cache operation is disabled). Though the pr ef etch operation uses the buffer as a cache, finding the requested data in the buffer is a prefetch hit, not a cache operation hit.
To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.
The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11). When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous
blocks from the disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur.

6.1 Error rates

The error rates stated in this manual assume the following:
• The drive is operated in accordance with this manual using DC power as defined in Section 7.3
• Errors caused by host system failures are excluded from error rate computations.
• Assume random data.
• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time.

6.1.1 Recoverable Errors

Recoverable errors are those detected and correcte d by the drive, and do not require user intervention. Recoverable Data errors will use Error Correction when needed. Recovered Data error rate is determined using read bits transferred for recoverab le errors occurring during a
read, and using write bits transferred for recoverable err ors occurring during a write.

6.1.2 Unrecoverable Errors

Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 1016 bits trans­ferred. Unrecoverable Data Errors resulting from the same cause are treated as 1 error for that block.
14 Savvio 10K.5 FC Product Manual, Rev. D

6.1.3 Seek errors

A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in 10
8
seeks. Unrecoverable seek errors
(Sense Key = 04h) are classified as drive failures.

6.1.4 Interface errors

An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error. The total error rate for a loop of devices is the sum of the individual device error rates.

6.2 Reliability and service

You can enhance the reliability of disk drives by ensuring that the drive receives adequate cooling. Section 7.0 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 9.2 provides recommended air-flow information.

6.2.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

These drives shall achieve an AFR of 0.44% (MTBF o f 2,000,000 hours) when operat ed in an environment th at ensures the HDA case temperatures do not exceed the values specified in Section 7.5.1.
Operation at case temperatures outside the specifications in Section 7.5.1 may increase the AFR (dec rease the MTBF).
AFR and MTBF statistics are population statistics that are no t relevant to individual unit s. AFR and M TBF spec­ifications are based on the following assumptions for Enterprise Storage System environments:
• 8,760 power-on hours per year
• 250 average on/off cycles per year
• Operating at nominal voltages
• System provides adequate cooling to ensure the case temperatures specified in Section 7.5.1 are not exceeded.

6.2.2 Preventive maintenance

No routine scheduled preventive maintenance is required.

6.2.3 Hot plugging the drive

Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the receiver of the next device in the loop must synchronize to a different input signal. FC error detection mecha­nisms, character sync, running disparity, word sync, and CRC are able to detect any error. Recovery is initiated based on the type of error.
The disk drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching the power or hot plugged. T he control line to an option al port bypass circuit (external to the drive), defaults to the Enable Bypass state. If the bypass circuit is present, the next device in the loop will continue to receive the output of the previous device to the newly inserted device. If the bypass circuit is not present, loop operation is temporarily disrupted until the next device starts receiving the output from the newly inserted device and regains synchronization to the new input.
Savvio 10K.5 FC Product Manual, Rev. D 15
The Pass-through state is disabled while the drive performs self test of the FC interface. The control line for an external port bypass circuit remains in the Enable Bypass state while self test is running. If the byp ass circuit is present, loop operation may continue. If the bypass circuit is not present, loop operation will be halted while the self test of the FC interface runs.
When the self test completes successfully, the control line to the bypass circuit is disabled and the drive enters the FC-AL Initializing state. The receiver on the next dev ice in the lo op must synchr onize to output of the newly inserted drive.
If the self-test fails, the control line to the bypass circuit remains in the Enable Bypass state.
Note. It is the responsibility of the systems integrator to assure that no temperature, energy , voltage hazard, or ESD poten-
tial hazard is presented during the hot connect/disconnect operation. Discharge the static electricity from the drive carrier prior to inserting it into the system.
Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is
required to insure data integrity.

6.2.4 S.M.A.R.T.

S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow you to back up the data before an actual failure occurs.
Note. The drive’s firmware monitors specific attributes for degrada tion over time bu t can’t predict instantaneous drive fail-
ures.
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating per­formance of the drive and the thresholds are op tim ized to minimize “false” and “failed” predictions.
Controlling S.M.A.R.T.
The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feat ure. Setting the DEX­CPT bit disables all S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs normal read and write operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line functions.
You can measure off-line attributes and force the drive to save the data by using the Rezero Unit comma nd. Forcing S.M.A.R.T. resets the timer so that the next scheduled interrupt is in one hour.
You can interrogate the drive through the host to determine the time remaining before the ne xt scheduled mea­surement and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This allows you to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the timer.
Performance impact
S.M.A.R.T. attribute data is saved to the disk so that the events that caused a pr edictive failure can be recre­ated. The drive measures and saves parameters once every hour subject to an idle period on the FC-AL bus. The process of measuring off-line attribute data and saving data to the disk is interruptable. The maximum on­line only processing delay is summarized below:

Reporting control
Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method. For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field contains the type of predictive failure that occurred. The error code is preserved through bus resets and power cycles.
Determining rate
S.M.A.R.T. monitors the rate at which errors occur and signals a pr edictive fai lure if the rate of d egrad ed er rors increases to an unacceptable level. To determine rate, error events are logged and com pared to the number of total operations for a given attribute. The interval defines the number of opera tions o ver whic h to me asure the rate. The counter that keeps track of the current numbe r of operations is referred to as the Interval Counter.
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for the current interval. This counter is referred to as the Failure Counter.
Error rate is the number of errors per operation. The algor ithm that S.M .A.R.T. uses to record rates of error is to set thresholds for the number of errors and their interval. If the number of errors exceeds the threshold before the interval expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is considered to be acceptable. In either case, the inter­val and failure counters are reset and the process starts over.
Predictive failures
S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firm­ware keeps a running count of the number of times the error rate for each attribute is unacceptable. To accom­plish this, a counter is incremented e ach time the erro r rate is unacceptable and decremented (not to exceed zero) whenever the error rate is acceptable. If the counter continually increments such that it reaches the pre­dictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute.

6.2.5 Thermal monitor

Savvio 10K.5 FC drives implement a temperature warning system which:
1. Signals the host if the temperature exceeds a value which would threaten the drive.
2. Signals the host if the temperature exceeds a user-specified value.
3. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.
A temperature sensor monitors the drive temperature and issues a warning over the interface when the tem­perature exceeds a set th reshold. The t emperature is measured a t power-up an d then at te n-minute inter vals after power-up.
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the speci­fied limit in compliance with the SCSI standard. The drive temperature is reported in the FRU code field of mode sense data. You can use this information to determine if the warning is due to the temperature exceeding the drive threatening temperature or the user-specified temperature.
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled b y the Method of Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).
The current algorithm implements two temperature trip points. The first trip point is set at 68°C which is the maximum temperature limit according to the drive specification. The second trip point is user-selectable using the Log Select command. The reference temperature parameter in the temperature log page (see Table 1) can
Savvio 10K.5 FC Product Manual, Rev. D 17
be used to set this trip point. The default value for this drive is 68°C, however, you can set it to any value in the range of 0 to 68°C. If you specify a temper ature greater than 68°C in this field, the temperature is rounded down to 68°C. A sense code is sent to the host to indicate the rounding of the parameter field.

6.2.6 Drive Self Test (DST)

Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level.
There are two test coverage options implemented in DST:
1. Extended test
2. Short test The most thorough option is the extended test that performs various tests on the d riv e a nd sca ns ev er y lo gic al
block address (LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media surface, but does some fundamental tests and scans portions of the media.
If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from service and return it to Seagate for service.
6.2.6.1 DST failure definition
The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional failure is encountered during DST. The channel and servo parameters are not modified to test the drive more stringently, and the number of retries are not reduced. All retries and recovery processes are enabled during the test. If data is recoverable, no failure condition will be reported regardless of the number of retries required to recover the data.
The following conditions are considered DST failure conditions:
• Seek error after retries are exhausted
• Track-follow error after retries are exhausted
• Read error after retries are exhausted
• Write error after retries are exhausted Recovered errors will not be reported as diagnostic failures.
6.2.6.2 Implementation
This section provides all of the information necessary to implement the DST function on this drive.
6.2.6.2.1 State of the drive prior to testing
The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a format, or another DST. It is the responsibility of the host application to determine the “not ready” cause.
While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive.
18 Savvio 10K.5 FC Product Manual, Rev. D
A Drive Not Ready condition is reported by the drive under the following conditions:
• Motor will not spin
• Motor will not lock to speed
• Servo will not lock on track
• Drive cannot read configuration tables from the disk
In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code.
6.2.6.2.2 Invoking DST
To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short test or 010b for the extended test) in bytes 1, bits 5, 6, and 7.
6.2.6.2.3 Short and extended tests
DST has two testing options:
1. short
2. extended
These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan
segment.
Short test (Function Code: 001b)
The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A complete read/verify scan is not performed and only factual failures will report a fault condition. This option provides a quick confidence test of the drive.
Extended test (Function Code: 010b)
The objective of the extended test option is to empirically test critical drive componen ts. For example, the seek tests and on-track operations test the positioning mechanism. The read operation tests the read head element and the media surface. The write element is tested through read/write/read operations. The integrity of the media is checked through a read/verify scan of the media. Motor functionality is tested by default as a part of these tests.
The anticipated length of the Extended test is reported through the Control Mode page.
6.2.6.2.4 Log page entries
When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-test parameter block at the b eginning of the se lf-test result s log par ameter section of the log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 param­eter blocks in the log page. If there are more than 20 parameter blocks, the least recent parameter block will be deleted. The new parameter block will be initialized as follows:
1. The Function Code field is set to the same value as sent in the DST command
2. The Self-Test Results Value field is set to Fh
3. The drive will store the log page to non-volatile memory
After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self­Test Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the last 20 self-tests performed by the drive. Th e se lf- te st r esults value is a 4-bit field that reports the results of the test. If the field is set to zero, the drive passed with no errors detected by the DST. If the field is not set to zero, the test failed for the reason reported in the field.
Savvio 10K.5 FC Product Manual, Rev. D 19
The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC, ASCQ, and FRU are used to report the failure condition.
6.2.6.2.5 Abort
There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message to abort the diagnostic.
You can abort a DST executing in background mode by using the abort code in the DST Function Code field. This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).

6.2.7 Product warranty

Beginning on the date of shipment to the customer and continuing for the period specified in your purchase contract, Seagate warrants that each product (including components and subassemblies) that fails to function properly under normal use due to defect in materia ls or workman ship or due to n onconformance to the applica­ble specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer , if returned by customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer. For more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate products on your pur­chase documentation.
The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. You can also determine remaining warranty using the Seagate web site (www.seagate.com). The drive serial number is required to determine remaining warranty information.
Shipping
When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Sea­gate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty.
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in tran­sit. Contact your authorized Seagate distributor to purchase additional b oxes. Seagate recommends shipping by an air-ride carrier experienced in handling computer equipment.
Product repair and return information
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.
Storage
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives should be stored in the original unopened Seagat e shipping packaging when ever possible. Once the drive is removed from the Seagate original packaging the recommended maximum period between drive operation cycles is 30 days. During any storage period the drive non-operational temperature, humidity, wet bulb, atmo­spheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

7.0 Physical/electrical specifications

This section provides information relating to the physical and electrical characteristics of the dr ive.

7.1 PowerChoiceTM power management

Drives using the load/unload architecture provide programmable power management to tailor systems for per­formance and greater energy efficiency.
The table below lists the supporte d PowerChoice mod es. The further you go down in the t abl e, the more power savings you get. For example, Idle_B mode results in greater power savings than Idle_A mode. Standby modes results in the greatest power savings.
PowerChoice modes
Mode Description
Idle_A Reduced electronics
Idle_B Heads unloaded. Disks spinning at full RPM
Idle_C Heads unloaded. Disks spinning at reduced RPM
Standby_Y Heads unloaded. Disks spinning at reduced RPM
Standby_Z Heads unloaded. Motor stopped (disks not spinning)
PowerChoice can be invoked using one of these two methods:
• Power Condition mode page method—Enable and initializ e the idle cond ition tim ers an d/or the standby con ­dition timers. The timer values are based on the values set in the Power Condition mode page.
• START STOP UNIT command method—Use the START ST
OP UNIT command (OPERATION CODE 1Bh).
This allows the host to directly transition the drive to any supported PowerChoice mode.
If both the Power Condition mode page and START ST
OP UNIT command methods are used, the START STOP UNIT command request takes precedence over the Power Conditio n mode p age power control and may disable the idle condition and standby condition timers. The REQUEST SENSE command reports the current PowerChoice state if active and also the method by which the drive entered the PowerChoice state.
When the drive receives a command, all power condition timers are suspended if they wer e enabled via the Power Condition mode page. Once all outstanding commands are processed, the power condition timers are reinitialized to the values defined in the Power Condition mode page.
Savvio 10K.5 FC Product Manual, Rev. D 21
